Title: METHOD AND APPARATUS FOR CONTROLLING AGGREGATE INTERFERENCE IN A COGNITIVE RADIO NETWORK
Abstract:
In accordance with an example embodiment of the present invention the application discloses a method and an apparatus for receiving a resource request (401 ); receiving information about locations of at least two white space devices; associating a location of a first white space device with a first maximum interference (402); associating at least one location of at least one second white space device with at least one second maximum interference (402); identifying one or more focal points based on the location of the first white space device and the at least one location of the at least one second white space device (404); calculating a maximum permitted power level (405) for the first white space device at least partly based on determining an aggregate interference level caused by the two white space devices at the one or more focal points; and informing the maximum permitted power level to the first white space device (406).
